In each of the cases on which he has been arraigned, Martinez is accused of forcing himself on
teenage girls after meeting them on the social media website Facebook.

During an interview with Bethlehem police in the original two cases, Martinez allegedly admitted to
both incidents. He claimed to have a sex addiction and be unable to control his body.

The Northampton County District Attorney's Office believed Martinez likely had more victims beyond the original two and pleaded during a news conference for others to notify authorities. As of Feb. 11, six more victims had stepped forward. The charges filed today are the first against Martinez since his Feb. 6 arrest.

Martinez was arraigned today before District Judge Roy Manwaring on
charges of rape and indecent assault for an alleged 2011 attack; and before District Judge Nancy Matos Gonzalez on charges of rape,
sexual assault, aggravated indecent assault and indecent assault for an alleged June 19 attack. A combined bail for each incident was set at
$525,000.

He's due to be arraigned on the third new case early
Thursday morning before District Judge Joseph Barner. Those charges stem
from an alleged incident Jan. 3 in Freemansburg and include rape, indecent
assault, involuntary deviate sexual intercourse and sexual assault,
court records show.

17 and pregnant

One of the victims, who was 17 at the time of the alleged rape, came to police a day after the Feb. 7 news conference, court records say.

She told police that she started speaking with Martinez in April 2011 after he sent a Facebook friend request, commenting that she was "pretty" in some of her online photos. The victim said the two spoke often through text messages and decided to meet up in person at McDonald's on Wyandotte Street in Bethlehem, court papers say.

Martinez allegedly drove the girl to his Maple Street apartment and parked his car on a corner. Court papers say he climbed onto the girl, despite her protests and grabbed her face for a kiss. After the assault, the victim told Martinez she only wanted to be friends.

In December 2011, Martinez again contacted the 17-year-old, records say. She was seven months pregnant at the time and agreed to meet with him after he sent her a message that said, "I miss you," according to the court records.

Martinez allegedly forced himself on her after rubbing her belly to feel the baby. Court papers say the victim tried to protect her stomach during the struggle, because she feared for the child. After the assault, Martinez allegedly sent the girl a text message that said "never contact me again."

'Had a look on his face'

Another 17-year-old victim called police on the same day as the news conference about Martinez. She said she was raped June 19 while she was four months pregnant, court papers say.

The victim's story mirrored those of the other accusers. She had met Martinez online through Facebook and agreed to meet him in person at her home, court papers say.

Martinez told her she was "beautiful" during a walk around the neighborhood. After a trip to the McDonald's on Wyandotte Street, the victim told police that Martinez took them to Lookout Drive on Lehigh University property, court records say.

While in the vehicle together, Martinez tried to kiss the victim, but she pushed him away, court papers say.

"This is not supposed to happen," she said, according to court records. "We are friends."

Something about Martinez changed then, the victim said. She told police that "he had a look on his face -- it didn't seem like it was David," according to court papers.

Records say Martinez grabbed the girl's head and forcibly kissed her. He allegedly pinned her to the seat and raped her, despite her protests to stop. The victim told police she, too, was scared for her baby, court papers say. Martinez was allegedly putting so much weight on her body that the victim's abdomen hurt.

When he climbed off the victim, she screamed for him to take her home, court records say. Martinez dropped her off at her residence and then drove away, court papers say.

Later that night the victim said she received a text message from Martinez that allegedly read, "I am sorry again, please forgive me. I don't want you to hate me. Can you please keep this between us because that really definitely was not me? I am sorry."
